Abstract (en)
[origin: EP3611203A1] The present invention relates to a composition for preparing flexible foams and the application thereof. The composition comprises the following components: a. an isocyanate mixture comprising: a1) an aliphatic and/or alicyclic isocyanate monomer, and a2) an aliphatic and/or alicyclic isocyanate trimer, wherein the mass ratio of said monomer to said trimer is in a range of 3:1-200:1; b. a polymer polyol mixture comprising: b1) a first polyether polyol having a number average molecular weight of not less than 3000 g/mol with an ethylene oxide content of 5-20 wt.%, b2) a second polyether polyol having a number average molecular weight of not less than 3000 g/mol with an ethylene oxide content of more than 60 wt.%, wherein the mass ratio of said first polyether polyol to said second polyether polyol is in a range of 4:1-100:1; c. an isocyanate-reactive group comprising compound having a number average molecular weight of 32-400 g/mol; d. a catalyst; e. a foaming agent; and f. optionally, an additive; wherein said composition has an isocyanate index of 70-120.
